Proven in the lab to be strong enough to support 880 LB(400 KG). The double-layered straps are made from nylon webbing, with each anchor loop marked by double stitching lines and paired with two corrosion-resistant carabiners.

The smooth Zelkova Sinica wooden rings provide a superior grip, absorbing moisture without the need for chalk.
